Owain thank you for a very comprehensive answer to my question . I had no idea about the run down period and am glad I asked , I have a tractor in the front of my workshop with a 12v battery so I will use this with an occasional run to charge the battery .

A very interesting discussion I have had my eye on these for some time.I have one question do they require a 12 of 24 volt battery or are there mains ones or could I get or build a 12 v power supply.

Thank you for your reply which I found most informative. The last paragraph might point toward an answer to what is happening, . I have a noise like running water in the loft and a new radiator I fitted is stone cold The previous owner of the house said they had always had problems with that radiator. Is it possible that the pressure of the pump is being wasted

Any heating engineers here. The circulating pump on my fairly old oil heating system died and when I replaced it I noticed that although it was in the returm pipe it was pumping away from the boiler. Surely this cannot be correct What would happen if I turned it round to pump into the boiler. Could it aause any calamities somewhere else in the system? .

Unless you can find something with this thread you will need to get someone to screw cut it on a lathe as a tap of this size would cost a fortune .

When I wrote the previous post i was rather hoping what I said was correct, although I had doubts. I am afraid you have just confirmined what I suspected and it fits in with my experiences in various types of gun club for over fifty years. Shooters are becoming less tolerant of others shooting disciplines and interests and this weakens our negotiating position in opposing restrictions on our sport.

I cannot understand why black powder shooters should not be welcome at any form of country event unless it is the dreaded health and safety brigade interfering again . I am an engineer and find it difficult to stand beside a steam engine boiler as I know the carnage a boiler explosion causes ,so why all the nonsence about black powder. Clouds of smoke and noise are surely an exageration .

Axminster saws start outside your price range but Screwfix have two small saws which are well priced and quite small

The bell was angled so that the bullet would go through the brain and into the spinal cord . Greener described the bell as an early type of sound moderator . This humane killer was used by vets for many years untill the captive bolt gun was introduced and deamed to be safer.

Guncotton was tried after its introduction and was discovered to be too violent for firearms. I have done more research and discovered that you can indeed purchase up to 500 grams of potassium nitrate without a licence, but you would still have to have a permission to purchase explosives for purposes other than blasting from the police to hold the gunpowder. The problem here is that you have to include a supplier and I wonder how the police would react to the idea of making your own.

Strange someone would mention agricultural uses for saltpeter, When I was a teenager some fifty years ago and into pipe smoking I grew some tobacco in a kind of poly tunnel . Yes in N Ireland! The experiment worked but the tobacco was mediocre at best. and not worth the effort. One of the problems was that saltpeter was the the recommended fertiliser and I had to apply for a licence. to buy it.

No Body Important I assume you are in N America as you have freedom to make powder. I took a brief look at the leglislation in the U.K.and discovered that a licence is required to buy potassium nitrate as it is called an explosive precursor grade 1 .I can omly imagine that the Health and Safety exeutive would add another handful of rules and we would still be faced with transport problems.

I have never tried pyrodex but Henry Krank suggests that it is not suitable for original guns. The rules are not so tight for pyrodex but it is more corrosive than black powder and more expensive. Having mentioned Krank who offers a wide range of black powders including some made in Switzerland I feel something is strange that it can be transported accross the eu but not to N I reland.

I have just tried Field and Stream and the Reload shop and been told that they cannot get black powder because of the trouble and costs involved.

Black powder appears to have become almost impossible to obtain due to new regulations about shipping and transport. I would like to ask our N Ireland members if anyone knows of a dealer who stocks it.
